BANDED STAVE-PIPE.

Specification of Letters Patent.

Patented April 30, 1907.

Application filed March 29,1906. Serial No. 308,629.

To all whmn it may concern:

Be it known that I, JOHN S. F. MARxs, a citizen of the United States, residing at Olympia, in the county of Thurston and State of ashington, have invented certain new and useful Improvements in Banded Stave-Pipes, of which the following is a specification, reference being had therein to the accompanying drawings, in which Figure 1 is a side elevation of a stave pipe to which my invention is applied; Fig. 2, a fragmentary sectional view taken through 22 of the same and Fig. 3, a perspective view of a band-securing clip drawn to an enlarged scale.

This invention has relation to pipes constructed of wood staves; and its principal object is to provide an inexpensively applied and reliable means for securing a stave-binding band in its wrapped position upon the ipe.

To attain this and other ends, the invention consists in the peculiar construction and combination of devices which I will now describe with reference to the said drawings.

The letter A designates a section of a wood. pipe composed of staves B and maintained in its proper shape by a metallic band C coiled spirally thoreabout. This band is of a ribbon like configuration, that is to say, of an approximately oblong cross section, and has at least one flat face which, in winding, would be disposed in juxtaposition with the peripheral surface of the pipe and afford an extended bearing thereagainst.

Prior to winding, the band at a short distance from its advance end, is given a bend, as at I), in an oblique direction to effect a twist to the extremity E which is placed upon and adjacent to the end of the pipe in an approximately longitudinal direction and is desirably affixed by a staple F driven into the wood. The main portion of the band is then tightly coiled about the pipe toward the other end encompassing the part E and pressing the advance edge E into the pipe wood, see Fig. 2, to make a rigid anchorage for the band at that end of the pipe.

The band is secured to the pipe in proximity of its other end and likewise to the adjoining coil part by a clip H and has the extremity I folded back and secured by a staple K, as represented in Fig. 1. The said clip is desirably of malleable sheet metal and formed with a central bed portion L, and ears M and fangs N which respectively extend above and below the said bed portion and are advantageously arranged upon the diagonally opposite corners, as clearly shown in Fig. 3. In practice the clip is placed in posi tion against the pipe before the winding is completed so that the last entire coil will pass over the bed portion thereof and, in being wound thereover under pressure, cause the fangs to penetrate the pipe therebelow and the terminal portion of the band is likewise seated along side of this coil on the bed when the clip-ears M are turned over to embrace both such parts of the band, and the extremity I folded back and stapled to the pipe as before explained.

A band formed and applied, as aforesaid, lies snugly against the pipe and is capable of being treated with a protective coating, as of a mixture of asphaltum and saw-(lust, for example, with less liability of the coating being cracked by a disturbance of the band, as is common with round wire wrapping when being transported or otherwise handled.

Having described my invention, what I claim, is-

1. A wire-end securing clip comprising a rectangular-shaped piece of metal, upwardly projecting ears arranged on two of its opposite corners, downwardly projecting ears on the other two of said corners, said downwardly projecting ears adapted to engage the body around which the wire is wrapped, and the upwardly extending ears adapted to be bent over and engage said wire, substantially as described.

2. The combination with a stave-pipe, and the winding-band, of a clip comprising a rectangularshaped bed-plate, having downwardly extending pipe engaging ears on each of two of its corners, and upwardly extending ears on each of its other two corners, said second named ears adapted to engage said winding band.

In testimony whereof I a'liix my signature in presence of two witnesses.

JOHN S. F. MARKS.
